clear that the Bora 50 gives up some ground to toroidal rims, and therefore, is unlikely to woo aero-weenies. At face value, these results fail to live up to Campagnolos claims for AC3 ( up to 43 increase in braking performance over previous models but after discussing the results with the company, it was clear there was a significant difference in the testing conditions. Everyone will now get the benefits of tubeless as well, with the Bora WTO wheels deep tubeless rim profile, hooked bead, and tire locking shoulder lip. In this regard, the Boras were no better or worse than any other 50mm rim Ive ridden. The right wheels can make a huge difference in both of those categories. I came down a slight hill onto the bike path and immediately saw tree roots coming through the cement. The geometry of the rear hub adds to the robustness of the rear wheel. The drive-side bearings sit below the ratchet ring. Before the ride, the Bora Ultra 50 wheelset shares almost all of the same features as the.

With the move to a more aero optimized uppsala länstrafik kontakt design, Campy sees this as an eventual replacement to the current Bora Ultra. There are conversion cassettes you could run that are compatible with a Campagnolo drivetrain but fit on a Shimano freehub body. But aerodynamic optimization had stagnated until now. Where once the brake track was smooth, AC3 is textured with small arcs that have been cut into the resin. The Bora Ultra 80 is designed to be paired in both function and appearance with 50mm-deep Bora wheels. The arrangement of parts is identical for the rear hub. For me, the winning feature for Campagnolo is the aluminum brake track on the Bullet Ultra. Thus, the Bora Ultra 50 will not tick the boxes for every buyer, especially those concentrating on rim profiles that have been fastidiously refined to maximise marginal aerodynamic gains. Hardly, but it does make the wheels feel a little more special. The thing is, I dont generally need to be my fastest up climbs. Campagnolos AC3 brake track features a subtle texture created by a series of arcs etched in the resin. Designed to give results in any weather on any terrain, the Ultra 35 is extremely versatile.
In the case of the Bora 50, it is significantly higher: 70 of the drive-side tension. I found the tyres were a pretty tight fit, so a set of levers might be needed when installing and/or removing the tyres. The Bora Ultra 50s remained smooth and comfortable at high speeds.
